8. Primary / Secondary IDE connectors (Two 40-pin Blocks)
These connectors support the provided IDE hard disk ribbon
cable. After connecting the single end to the board, connect the
two plugs at the other end to your hard disk no space(s) . If you
install two hard disks, you must configure the second drive to
Slave mode by setting its jumper settings. BIOS now supports
SCSI device or IDE CD-ROM boot up (see "HDD Sequence SCSI/
IDE First" & "Boot Sequence" in the BIOS Features Setup of the
BIOS SOFTWARE) (Pin 20 is removed to prevent inserting in the
wrong orientation when using ribbon cables with pin 20 plugged).
Tip
:
You may configure two hard disks to be both Masters using
one ribbon cable on the primary IDE connector. You may in-
stall one operating system on an IDE drive and another on a
SCSI drive and select right one the through BIOS Fea-
ture Setup.
9. IrDA / Fast IR-Compliant infrared module connector - JIR1
This connector supports the optional wireless transmitting and
receiving infrared module. This module mounts to a small open-
ing on system cases that support this feature. You must also
configure the setting through UART2 Use Infrared" in Chipset
Feature Setup to select whether UART2 is directed for use with
COM2 or IrDA. Use the five pins as shown on the Back View and
connect a ribbon cable from the module to the motherboard ac-
cording to the pin definitions.
